Valiant Communications launches hardware-based zero-day mitigation solution
Valiant Communications Limited introduces a hardware-based cybersecurity solution to counter zero-day attacks, combining a honeypot decoy with physical network isolation. The system addresses the limitations of software defenses in critical infrastructure, where 48% of zero-days targeted enterprise tech in 2025. By physically severing compromised networks, the solution ensures compliance with global regulations including IEC 62443 and India's CEA Cyber Security Regulations.

Valiant Communications Limited has unveiled a hardware-based cybersecurity solution designed to mitigate zero-day attacks by physically isolating compromised networks. Announced on July 27, 2026, the architecture combines the VCL-Network MouseTrap, a decoy honeypot, with the VCL Network Isolation Kill Switch to detect and contain threats that bypass traditional signature-based defenses. This development addresses the escalating risk to critical infrastructure, where software-only solutions often fail against sophisticated, state-sponsored actors.
The release comes amid a deteriorating global threat landscape. In the first half of 2025 alone, more than 23,600 vulnerabilities were published, marking a 16% increase over 2024. Nearly 30% of known exploited vulnerabilities were weaponized within 24 hours of public disclosure, and nearly 90 zero-day vulnerabilities were observed in active exploitation during 2025. Ransomware incidents spiked by 36%, with attackers increasingly targeting edge devices and operational technology (OT) environments. The financial impact is severe: the average cost of a data breach for US companies reached $10.22 million in 2025, while the global average stands at $4.44 million.
Conventional security measures rely on recognizing known threats, leaving them blind to zero-day exploits. In 2025, 48% of tracked zero-days targeted enterprise-grade technology, with security and networking devices accounting for over 60% of these attacks. The average time to identify a breach remained at 258 days, with containment taking 64 days. VCL’s solution operates on a different principle: it does not need to recognize the attack signature but instead detects unauthorized behavior through decoy systems.
The VCL-Network MouseTrap acts as an advanced honeypot, impersonating critical assets such as servers, protection relays, RTUs, payment gateways, and SCADA nodes. When a zero-day exploit probes this decoy, it reveals itself immediately. The MouseTrap generates audio-visual alarms, SNMP traps, and out-of-band security alerts. Crucially, its RS-232/RS-485 output is directly wired to the VCL Network Isolation Kill Switch (models VCL-2702/5052/5054), triggering automated isolation with zero human delay.
Upon detection, the Kill Switch physically severs the LAN from the WAN or isolates specific servers and data storage assets in milliseconds. Unlike software commands, which can be intercepted or disabled by malware, this hardware-enforced disconnection is independent of the operating system or management plane. The device is fail-safe; if it loses power or suffers a control card failure, any port already in isolation mode remains isolated, preventing attackers from recovering connectivity by disrupting the device itself.
Threat Response Architecture
| Threat Stage | VCL-MouseTrap Response | VCL Kill Switch Response |
|---|---|---|
| Zero-day probes network | Decoy lures and logs attacker | Standing by |
| Intrusion confirmed | Fires alarm + triggers Kill Switch via serial | Physically isolates LAN/WAN and critical digital assets |
| Attacker attempts lateral spread | Non-volatile forensic log captures IP fingerprint | Network segments remain physically severed |
| Incident response | Full access log for digital forensics | Isolated mode maintained until manual release |
This architecture is particularly relevant for OT environments in power utilities, water treatment plants, substations, defense installations, banking infrastructure, and data centers. Many OT systems cannot run endpoint agents, cannot be patched rapidly, and cannot tolerate the latency introduced by software-based security inspection. State-backed campaigns have focused specifically on these industrial environments, with nearly half of attacker groups involved in 2025 campaigns linked to state-sponsored or hacktivist entities.
Regulatory Compliance
VCL’s solution supports compliance with several key regulatory frameworks:
- International: IEC 62443 (Industrial Automation and Control Systems security) and IEC 61850 (substation communication security), which mandate network segmentation and anomaly detection.
- India: NCIIPC guidelines, CERT-In Directions (April 2022), CEA Cyber Security Regulations (2024, enforceable from April 2027), and NCRF 2024, all requiring OT network segregation and incident response capability.
- UK: NCSC CAF 4.0 and the Cyber Security and Resilience Bill 2025, which require critical infrastructure operators to demonstrate active intrusion detection and isolation.
Valiant Communications designs and manufactures advanced IT/OT communication, synchronization, protection, transmission, NAS, SAN data storage, and cybersecurity equipment. With installations in more than 110 countries, its technologies serve power utilities, railways, oil & gas, airports, defense, and SCADA systems globally.
